To all whom it may comer/w Be it known that I, NmoLAUs BASEIiAQH,

a citizen of the German Republic, residing at Potsdam, Germany, have invented new 5 and useful Improvements in an.Anchor1ng Arran ement for Airships (for which I have filed an application in Germany on August 22, 1913), of which the following is a specification.

My present invention relates to an anchoring arrangement .for air-ships, and has for its object to provide improvements whlch ensure that thereby the air-ship is effectively protected against accidents caused by violent wind'sf In consequence of my novel arrangement the anchoring action may be easily and readily carried out. My invention consists in providing an anchoring point beneath the forepart of the shi as, for instance, on the prow of'the keel rame or beneath the front car, and pivotally joining this anchoring point directly to a suitable earth-anchor, whereby'the ship is enabled to vertically oscillate and horizontally revolve about this pivotal anchoring joint. As a suitable means for effecting this pivotal anchoring joint I may use an universal joint, a ball 'oint, a Cardan joint, of

' which one part is irectly, or by means of so an intermediate member, secured to the anchoring point of the air-ship, while the second part of said joint is directly, or by means of an intermediate member, secured to said earth anchor. Instead of providing said anchoring point at a downward projecting part of the ship prow, in order to allow the ship the necessary revolving and swinging play, I may dispose the said anchoring point directly beneath the fore part 40 of the carrying body of the ship and raise the earth anchor to such a height that the necessary revolving and swinging play is secured. Or I may provide the carrying body of the air ship with a dqwnward directed rigid structure the end of which is then pivotally connected to the earth anchor which need not project above the ground. .It is one essential feature of my present invention that the air ship is enabled to readily revolve and oscillate about the anchoring point and that this point is disposed beneath the front part of the air ship. Another essential feature of. my present invention is that the anchoring connection is secured by means of an universal joint which securely prevents any lon itudinal movements within the axis oft e ship body although it allows the ship the necessary revolving and swinging play.- By suitably adjusting the horizontal rudder of the air ship any contact of the rear of the ship with the ground can be easily prevented.

To carry my invention into effect I do not require high stationary columns which are expensive to erect and to maintain, and I do not require reenforced end constructions of the carrying body of the ship, since, with my invention the one part of the pivotal joint may be secured to some transversal frame work parts. of the carrying body, which, parts'for that purpose, may be somewhat stronger constructed than the others if considered necessary.

In order to render my invention quite clear I have illustrated some embodiments 7 of the same in the accompanying drawings, by way of example. v

Fig. 1 is a diagrammatic elevation of an air-ship anchored directly to the ground with the front end of its stiffening frame.

Fig. 2 illustrates the application of a raised and earth-anchored structure.

In Fig. 3 the front car is provided with one part of the pivotal joint and in Fig. 4 this part of the pivotal joint is secured directly beneath the prow of the carrying body of the ship, this arrangement necessitating the application of a raised and earth-anchored structure.

In Fi 5 a downward tureis xedly secured ship body. And in Fig. 6 the anchoring arrangement illustrated in Fig. 4 is shown on an enlarged scale.

In the examples shown in the drawings the air ship is designated a and is provided with one part 6 (compare Fig. 6) of an universal joint, the supplementary part 0 being either secured directly to theearth anchor or to a raised structure 03. The part b may be fixed to the front end of the stiffeningframe work? as shown in Fig. 1, or to the front end of the keel frame as in Fig. 2. In this case, the supplementary part c of the universal joint is fixed at the termination of a raised structure d secured to the ground by means of earth projecting struc- 9 to the prow ofthe anchors e, e (compare Fig. 6). The part b of the universal joint may be secured to the front end of the front car as in Fig. 3 and directly connected to the earth anchors e, e by means of the supplementary part 0 of the universal joint. If the part b is fixed directly to the lower surface of the body of the air ship, the raised structure d must then be of such a height that the front car is prevented from touching the ground (see Fig. 4). In this case there must be a very reliable connection between the car and the main body of the ship. I may obtain the same eflect by providing a rigidly secured structure d beneath the fore part of the main body of the ship, as shown in Fig. 5, which eliminates the necessity of providing such structures on the ground on which only ordinary earth-anchors are required.

By suitably adjusting the horizontal rudder f the air ship can readily be maintained in the inclined position shown in the drawings.

I am aware that other modifications may be made within the scope of my invention.

What I claim as my invention and desire to secure by Letters Patent of the United States, is

thefront of the ship and forming a rigid projection of said part, an anchoring device constructed and secured so as to form a rigid projection of the anchoring place, and a pivotal connection between said anchoring point of said ship part and said anchoring device, whereby said ship is allowed a revolving and oscillating movement about the axis of said pivotal connection.

2. An anchoring arrangement for airships, comprising, in combination, a downward projecting structure at the front part of the ship, said structure being rigidly secured to said ship and of such a length that its termination forms the lowest point of'the front part of the ship, a part of an universal joint rigidly connected to the lower termination of said structure, an anchoring device constructed and-secured so as to form a rigid anchor at the anchoring place, and a supplementary part of the universal joint rigidly connected to said rigid anchor at the anchoring place.
